In catering operations, oil and grease are often byproducts of cooking processes, especially when frying foods. When these materials are disposed of improperly, they can cause environmental pollution and blockages in drainage systems. Proper oil-water separation ensures that oils, fats, and greases are effectively removed from wastewater before it is discharged into sewage systems or the environment. This is essential for:
Environmental Compliance: Proper treatment helps businesses avoid fines and penalties related to wastewater disposal.
Maintenance Costs: It prevents blockages and costly repairs to plumbing systems.
Operational Efficiency: Helps in managing waste efficiently, contributing to a cleaner and safer kitchen environment.

2.1. Gravity-Based Oil-Water Separators
Gravity-based oil-water separators are the most common and cost-effective choice for many catering businesses. These systems rely on the natural difference in density between water and oil. Since oil is less dense than water, it floats to the top of the separation chamber, while the water is collected at the bottom.
These separators usually consist of a tank where wastewater is fed in. The oil rises to the surface and is skimmed off, while the water flows out. They are suitable for small to medium-scale catering businesses and are simple to maintain.
2.2. Coalescing Plate Separators
Coalescing plate separators use a series of specially designed plates to increase the surface area for oil droplets to join together, or coalesce. As the wastewater passes through the plates, smaller oil droplets merge into larger ones, which then rise to the surface more easily. These systems are ideal for applications where oil content is higher and need to be treated more efficiently.
These separators are more efficient than gravity-based systems and can handle higher volumes of wastewater, making them suitable for larger catering operations or food processing facilities.
2.3. Dissolved Air Flotation (DAF) Systems
Dissolved Air Flotation (DAF) systems are high-efficiency separators that use air bubbles to separate oils and other contaminants from wastewater. The process involves dissolving air into water under pressure and then releasing it into the wastewater. The bubbles attach to oil droplets, causing them to float to the surface for removal.
DAF systems are highly effective for separating oils from water, even in low concentrations, and are ideal for businesses with a high volume of wastewater or those needing to meet stricter environmental standards. However, DAF systems tend to be more expensive and require more maintenance compared to other options.
2.4. Biological Oil-Water Separators
Biological oil-water separators use bacteria or other microorganisms to break down oils and grease in wastewater. This type of separation is ideal for businesses seeking an eco-friendly solution. While effective in reducing oil content, these systems may require more time and specialized maintenance compared to mechanical separation methods.
They are typically used in conjunction with other systems to further treat wastewater before final discharge.
3.1. Volume of Wastewater
The amount of wastewater your business generates plays a significant role in determining the type and size of the oil-water separator you need. Small operations may find gravity-based separators sufficient, while larger businesses, such as banquet halls or food production facilities, may require more advanced systems like coalescing plate separators or DAF systems. Consider the peak wastewater volume your business generates to choose a system with adequate capacity.
3.2. Oil Content
The level of oil contamination in your wastewater also affects the choice of equipment. For lower levels of oil contamination, gravity separators or coalescing plate separators are usually sufficient. However, if the wastewater contains high concentrations of oil or grease, DAF systems may provide more effective separation.
3.3. Space Availability
Some oil-water separation systems, especially DAF and biological separators, require more space for installation and operation. Consider the available space in your kitchen or facility before choosing a system. Gravity-based systems tend to be more compact and easier to install in smaller spaces, while more complex systems may need dedicated areas.
3.4. Maintenance Requirements
Oil-water separation systems vary in maintenance complexity. Gravity separators require less maintenance, while systems like DAF may need more frequent attention to maintain their efficiency, particularly with regard to the air dissolution and skimming mechanisms. Consider the time and resources available for maintaining the system before making a choice.
3.5. Budget
The cost of oil-water separation equipment can vary significantly, with gravity-based systems being more affordable than advanced systems like DAF or coalescing plate separators. While initial costs are important, it’s also crucial to consider the long-term operating and maintenance costs to ensure that the equipment remains cost-effective over time.
3.6. Environmental Regulations
Ensure that the oil-water separation system you choose meets local environmental regulations for wastewater discharge. Some regions have strict standards for the allowable oil content in wastewater, and selecting an appropriate separator will help ensure compliance and avoid penalties. Advanced systems like DAF or coalescing plate separators are often necessary for stricter regulations.

Consider the volume of wastewater, oil content, available space, and long-term maintenance requirements before selecting the right equipment. Whether you choose a gravity-based separator for smaller operations or a more advanced DAF system for high-volume businesses, investing in quality oil-water separation equipment is crucial for ensuring the longevity and success of your catering operation.
An efficient workflow removes barriers to employee productivity and helps your team work cooperatively.
Catering equipment that improves your kitchen workflow can provide many benefits. For example, service trolleys can enhance hotel productivity with faster food delivery. Other catering appliances can decrease food waste and increase restaurant profitability as a result.
Improving the slower parts of your kitchen workflow with commercial equipment can take your business to the next level.
Organising and running a kitchen while delivering delicious dishes can be challenging. A well thought-out kitchen workflow plan will help you and your staff work efficiently and avoid crowded workspaces.
The basic workflow of a kitchen includes food preparation, cooking, plating and cleaning. Many other operations happen behind the scenes, but these are the main steps.
Visualise each of these steps and the equipment needed to complete them. Your kitchen should form a logical and efficient flow from each step to the next.
For example, the area where servers pick up orders should be close to the plating station so that finished dishes only move a short distance. Even if this strategy only cuts 10 seconds from your process, these savings add up quickly when serving many dishes per day.
Everything must run smoothly from opening to closing for your kitchen workflow plan to be a success. You may need to experiment with multiple arrangements to find what works best.
Prioritise the busiest parts of your kitchen, such as food prep areas, storage access and cooking appliances. These are elements that can have a big impact on productivity.
Understanding how each process works together will help you identify places for improvement. Once you identify shortcomings in your kitchen workflow, consider what catering equipment would benefit these areas.
Choosing the right catering equipment for your kitchen can feel overwhelming. Although there are a lot of different models to choose from, the following will have an impact on the efficiency of your kitchen workflow:
1. Size and capacity

Before choosing any catering equipment, measure the area available in your kitchen. Knowing these measurements will help you pick catering equipment that fits and functions well for your space.
Larger machines generally have a greater capacity and can do more work in a given time period. Capacity can refer to the amount of storage room or food items cooked per hour, depending on the appliance.
Look for equipment with an ideal capacity for your needs. Too small, and your profitability will suffer. Too large, and you will spend more than you need.
Shop with suppliers who offer a wide range of sizes and capacities to find the best option for your business.
2. Quality and durability
Although it may be expensive, quality catering equipment can save you money in the long run.
Cheapest equipment is usually low-quality and fragile. Although it's cheaper to purchase, frequent repairs and replacements end up costing more.
Quality equipment that prioritises durability can often last as long as it’s well-maintained. It also protects your business from losing customers or productivity due to unexpected breakdowns.
Cutting corners is not smart when choosing commercial equipment for your business.
3. Customisability
Customisable equipment can help save time, effort and money by adjusting to your needs. It also allows for more flexibility in meeting customer demands.
Customisation makes adding new menu items, changing recipes and following trends easier with their adaptability. Customisable equipment allows you to update your kitchen workflow without needing a new set.
This helps professional kitchens provide customers with diverse and changing options. Shopping with quality suppliers is the best way to find a broad range of customisable products.
Besides thorough staff straining, giving your team the right tools is the best method for maximising kitchen efficiency.
Staff training improves the efficiency of your workers and the right catering equipment helps your team achieve the most efficient kitchen workflow.
Here are some appliances worth considering for improving productivity:
Planetary mixers can speed up the preparation of many recipes. They reduce workloads and allow chefs to focus on other tasks, leading to more efficient use of their time.
Food processors are great for quickly chopping vegetables or blending sauces, which helps save time. They’re also highly customisable, allowing chefs to adjust settings based on their needs. This flexibility can help boost productivity when preparing dishes in the kitchen.
High-quality ovens are incredibly versatile appliances, especially combi steam oven models. These genius machines can bake, boil, stew, braise and sear. This versatility improves productivity as chefs don’t need as many pieces of equipment for various cooking processes.
Dishwashers are necessary for any professional kitchen as they provide a fast and efficient way to clean dishes without any manual labour. Professional dishwashers are designed for many purposes, from small glass washers to large pass through dishwasher models.
These are just the most common machines for improving productivity. Explore the full range of commercial appliances to find more ways of improving your kitchen efficiency.
Once you have all the right catering equipment, it’s time to arrange it into a layout that allows for a fast-paced workflow. Finding the most efficient kitchen workflow plan is an ongoing effort. It takes a lot of trial and error to find the best process.
There’s no one-size-fits-all kitchen workflow but following these tips will help you develop one that suits your needs.
1. Plan ahead
Consider which areas have the highest foot traffic, which tools are used the most and where an order needs to go through each step of the workflow.
For example, you wouldn’t want your dishwashing station between where food is cooked and where it’s plated. Your cooking and cleaning staff would get in each other’s way. Dirty dishes can also create an opportunity for food contamination.
Visualising all the kitchen operations can help you anticipate problems and find solutions before they happen. Planning ahead will give your team a better chance of avoiding delays and keeping everything running smoothly.
2. Staff training
Professional kitchens work best with coordinated teamwork. Once you’ve developed a workflow, it’s important to train all your staff on how it works.
Your kitchen workflow will lose productivity if parts of the team don’t use it correctly. Each staff member should understand their place within the workflow and how it interacts with the other parts.
Encourage your staff to share ideas on improving the workflow. By working the kitchen workflow day after day, they’ll likely come up with ideas you haven’t considered.
Communicating effectively with your staff will help you get the best results from your workflow plan.
3. Organise workstations
The organisation of each station will play a huge role in its efficiency. Organisation systems are like mini workflows that keep each station running smoothly.
Items used the most frequently should be the most easily found. Think about stocking those items in multiple places if used in many parts of the kitchen. For example, disposable gloves are helpful to have available in several areas.
If certain tools are commonly used together, try to store them together as well. Arrange items so each one is visible to make it easy to find them.
Once you set up an organisation system, make sure to follow it and keep everything in its correct place.
4. Regular equipment maintenance
Maintaining your catering equipment is the best way to prevent breakdowns and keep your workflow running efficiently. It also helps to keep machines in good condition for many years, maximising the benefits of your purchase.
Anything used to cook or prepare food or drinks should get sanitised daily. Avoid harsh chemicals or abrasive materials, as these will likely damage or contaminate appliances.
Scheduling regular maintenance is the best way to make sure it isn’t forgotten. Make equipment maintenance a regular part of your routine to keep your tools in good condition.
Pay attention to manufacturer instructions on how to maintain your equipment and how frequently maintenance is needed.
